The AggSimulationTool has been implemented in Java to evaluate the following data-aggregation solutions: (i) Two-Tier Aggregation for Multi-target Applications (TTAMA); (ii) Data Aggregation for Multiple Groups (DAMiG) Minimum Spanning Tree (DAMiG-MST); (iii) DAMiG Shortest Path Tree (DAMiG-SPT); (iv) DAMiG selecting the parent with highest level of residual energy (DAMiG-MaxEnergy); and (v) Energy Efficient Spanning tRee (EESR).
- Firstly, you have to verify that java is running correctly in your computer.
- Simply, execute in terminal this command:
java -jar agg.jar - In the GUI you can set your simulation.
- This is a Java project that can be imported to Eclipse or Netbeans. To do so, you must follow the default procedure to import a Java project in Eclipse or Netbeans.
- The AggSimulationToolv1.2 has some configuration files that contain the basic settings for the simulation.
- These config. files should be stored in the directory named /settingFiles, which is located in the root dir. of the java project.
- The directories inside /settingFiles follow the following name convention: numberOFnodes+'-nodes'. For instance, '/settingFiles/11-nodes' should store the file simulation settings for the simulation of a network having 10 nodes (10 regular nodes).
- Each directory in '/settingFiles/' stores xml files following the name convention: numberOFgroups+'Groups.xml'. For instance, the file '1Groups.xml' stored in the path '/settingFiles/10-nodes/' should contain the setting for simulating a network compoused of 10 nodes and 1 group.
- Example of xml file setting (/settingFile/10-nodes/1Group.xml):

- Besides the xml files, it is necessary to set some configurations in the file: /src/code/Run.java.
- Set the number of nodes in the network. This number should be the same used on the xml files:
int netSize=101;//Default size. Netsizes: 32, 64, 128, 256
- Set the path variable according to your system:
path = "/Users/user/Documents/Dropbox/EclipseWorkspace/SimulationToolv1.2/";
